v3.1.1

FIX

• The newly added nutserverport argument was also trying to parse NUT_EXPORTER_SERVER env variable - this was fixed to be NUT_EXPORTER_SERVERPORT. Thanks for the bug report in #43, @LXGaming!

v3.1.0

New

• Add support for setting a port for the NUT server - see updated usage in README. Thanks for the idea in #39, @mpeter!

Misc

• Fix local Dockerfile build process to avoid crashes due to libc differences. Thanks for the PR #41, @mpeter!

v3.0.0

Breaking

• The following command line parameters are no longer available, but can stil be configured in the new web.config.file parameter (with many others):
  • web.tls.cert_file
  • web.tls.key_file
  • web.auth.username

New

• TLS and web setup is now using the Prometheus exporter-toolkit. This enables many new options and parameters to control the listening endpoint. Thanks, @SuperQ for the PR in #13!
• The exporter should now build for riskv64 architectures now. Thanks for the suggestion in #31, @clausecker! Note: releases are not yet provided for this architecture

Misc

• The sample dashboard now allows you to select the datasource. Thanks for #30, @paulfantom

v2.5.3

Fixed

• Document the NUT_EXPORTER_WEB_AUTH_PASSWORD environment variable in help message. Thanks, @v4rakh!

v2.5.2

Fixed

• To improve performance, the previous release cached handlers/collectors based on UPS name. Instead, it should cache by server/upsName. Thanks for the report in #28, @JonyEpsilon!

v2.5.1

New

• Add an error condition if the requested UPS name is not found in the NUT server on first scrape
• Debug logging will now log the names of valid UPSs found in the NUT server - search for "UPS name detection"

Fixed

• Reolve a problem introduced in the previous release if the same UPS is scraped concurrently - thanks for the report in #27, @tsull360!

Misc

• Efficiency: If no UPS name is provided in the scrape, but one is found when listing UPSs, save the name so future scrapes don't have to list UPSs again
• Cleanup: Make the code a bit more readable

v2.5.0

New

• Add a new flag to disable the meta-metric network_ups_tools_device_info - thanks for the suggestion in #26, @kondas!

Fixed

• Fix the broken promhttp_metric_handler_requests_total metric due to how the registry/prom handler was built. Thanks for the report in #25, @kondas!

Misc

• Correct a few go lint warnings
• Add an example Grafana dashboard and screenshot to the dashboard directory

v2.4.2

Fixed

• Sometimes the underlying NUT library provides the wrong type of the variable. Don't rely on this and instead always rely on Go types

v2.4.1

New

• Move to golang 1.18 for build and test suites

v2.3.5

Fixed

• Version output was not properly being set in go releaser. Thanks for the report in #19, @ymettier!
